latest on boost saga

Have you tried pinching off the hose from teh WGFV to the WG with a pair of vice grips or something and seeing what boost does then? Be careful doing this as you can hit overboost.
Have you tried a stock ECU?

oh, they agree it's hoaky, but they are at the point where the car is a losing investment for them and they do want me to have my boost.
if it comes to capping and springing, they said we can revisit later if the "mask" is not working out.

Personally my only issue with that is you are masking the problem - not
solving it.

Thanks Ed, i figure the hoses behind the head would have proven faulty
during the pressure test. they did replace every single hose in the
crankcase breather system too (they were totally rotted)
from my understanding, javad was doing grand stand passes down osgood blvd.
in fremont, enjoying the victory...until the car stopped hauling ass.
everyone was pretty pissed after that.
anybody have any thought as to the dangers of capping the N75 and installing
a 2.2bar WG spring? they said it's a little hoaky, but it will work.
computer won't be able to lower the boost though, which should be fine
under
most conditions, correct? just don't be stupid and stomp on it in hot
weather in stop and go traffic with the a/c on?

Have you been through all the little vacuum hoses behind the head?
I can't remember whether or not you commented on this during you saga.
When 034 swapped in the other ecu and were getting full boost for awhile,
did they only do that once and then tuck their tail and return to the shop
when they quit getting full boost?
I ask that because some vacuum leaks might be worse and much more noticeable
when the engine is good and hot. A cool-down cycle and another try w/o
changing anything else might give a little more information in terms of
another direction or set of circumstances to consider.
My Avant has flakey boost sometimes too. When it's good and cold out
before
the engine compartment has really gotten warmed up, I can get nice strong
full boost. Any other time, something is backing it off in the next gear
when I wale on it and then shift.
My intake air temp sensor has an extra set of wires spliced into it and
running along the same wiring harness to the firewall. I have several
receipts for IAT sensor replacement over the years. I figure they found
something flakey with the wiring. Or thought they did. I haven't traced
them to see what's up on the other end. If both sets are connected to the
ecu, then the reading might be hosed because of the extra resistance of the
extra wires. I'm actually not sure that's even theoretically possible,
but
it's a thought.
Anyway, good luck with your's. Over the years, I have grown more and more
fond of my V8q's because of troubleshooting turbo engine issues. It can
really drive you insane. The payoff is when a turbo 5 is healthy and
strong, even if only for a couple days, hours, minutes...
